BruceAWAY unfortunately your card can't be unlocked.
That card also can't be unlocked to something more than 8 pipes. Probably it could hides R480 which is very good overclocker. Try the core max. overclock with ATITool and if you figure out that it can reach 480-500MHz then return here. If it is capable of only 420-450MHz then it is R430 and you can't do more to improve the performance.
